我们开发了一种方法来评估微电网的潜力，以提高关键基础设施（CI）网络的弹性，并减轻灾难性故障在灾难情况下的影响。该方法使用一个优化模型来战略性地定位微电网和网络鲁棒性分析，以确定新的加强网络的好处。微电网的选址旨在确保社区最重要的设施在电网故障时有足够的电力提供服务。网络鲁棒性分析在网络的越来越大的部分失效的情况下评估加强的网络。该方法用于评估波多黎各ciciCI上微电网的安装情况，2017年飓风季节导致灾难性电网故障。研究小组在波多黎各进行了数据收集和实地研究，包括与灾害响应人员和CI经理的访谈。在安装微电网之前，小的中断可能会完全削弱配电系统。事实上，我们的数值实验表明，波多黎各30%的网络被破坏足以导致完全停电。另一方面，战略性地将微电网添加到30%的关键基础设施中可以确保系统的功能性，即使配电网络中80%的节点已经被摧毁。这些结果表明，在CI的鲁棒性和弹性方面，用微电网加强电网的潜在好处。
We develop a methodology to evaluate the potential of microgrids to increase the resilience of critical infrastructure (CI) networks, and mitigate the impact of catastrophic failure in disaster situations. The methodology uses an optimization model to strategically locate microgrids and a network robustness analysis to determine the benefits of the new reinforced network. The location of microgrids seeks to ensure that a community's most important facilities have adequate power to provide services in the event of power grid failure. The analysis of network robustness evaluates the reinforced network in the event of the failure of increasingly larger sections of the network. The methodology was used to evaluate the installation of microgrids on ciciCIs in Puerto Rico, where the 2017 hurricane season caused catastrophic grid failure. The research team conducted data collection and fieldwork research in Puerto Rico, including interviews with disaster responders and CI managers. Prior to the installation of microgrids, small disruptions could completely cripple the power distribution system. In fact, our numerical experiments show that the destruction of 30% of the network in Puerto Rico was sufficient to result in a complete blackout. On the other hand, strategically adding microgrids to 30% of critical infrastructure can ensure functionality of the system even when 80% of the nodes in a power distribution network have been destroyed. These results show the potential benefits of strengthening the power grid with microgrids in relation to the robustness and resilience of CIs.
